COMBINED GAS AND ELECTRIC LIGHT FIXTURE.

SPECIFICATION forming part of Letters Patent No. 307,879, dated November 11, 1884.

Application filed April 5, 1884. (X0 model.)

To all whom it may concern:

Be it known that I, LUTHER STIERINGER, of New York city, in the county and Stateof New York, have invented a certain new and useful Improvement in Combined Gas and Electric Light Fixtures, of which the following is a specification.

My invention relates to combined gas and electric light fixtures, made as complete integral structures, and having the wires for the electric lamps concealed from sight, such as described in my Patent No. 294,697; and it consists in improvements in details of construction, the object being principally to simplify the wiring of the structure and to make such wiring less liable to injury, and also to simplify and make more efficient the construction of the fixture itself. The fixture-is in the main like an ordinary gas-fixture,-the wires for the electric lamps being run through the space between the central sustaining stem or arm (the gas-pipe) and the ornamental cover ing surrounding such central stem or arm. At the lower or outer end of this central stem or arm is usually located a gas-distributing body, from which project arms carrying gas burners, and this gas-distributing body is surrounded by an ornamental body, which consists, principally, of a ring supported upon the gas-arms which run through it, and ornamental shells above and below this ring. In my patent referred to the electric-lamp arms also run through this ring to the gasb0dy, and are supported by the gas-body, such electriclamp arms not passing through to the interior of the gas-body, and hence not receiving gas therefrom, but being provided with side openings in the space between the gas-body and the external ring, through which side openings the wires pass into the arms, and through such arms to the electric-lamp sockets on the ends of the arms. By this invention, however, the electric-lamp arms do not extend to the gas-body, but only to the external ring, to which they are secured by being screwed into it, or by means of face-plates or otherwise. This construction enables the wiring of such electric-lamp arms to be more easily performed than where the wires pass through side openings in such arms. In gas-fixtures where there is a break in the ornamental covering, the

shells forming such break are centered upon the gaspipe, having inwardly-turned edges, which hug the gas-pipe closely, and the ornamental tubing above and below the break is received by shoulders formed on such shells. This is also the case with the shells which inclose the gas-body. In running the wires for the electric lamps through the space between the gas-pipe and the ornamental covering it is necessary to slot the edges of the shells hug. ging the gas-pipe, to make wireways, and since these shells are capable of turning upon the gas-pipe, the edges of the shells are liable to cut or abrade the insulating-covering of the wires, the result of which is to form a short circuit in the fixture; or the wires themselves might be cut by the edges of the shells. Now I key these shells upon the gas-pipe, preventing their turning upon the same, and, in addition, to better protect the wires, I provide wireways through the breaks, which keep the wires out of contact with the cutting-edges of the shells. Both of. these ends are accomplished by soldering or otherwise securing upon the gas-pipe one or more short sections of tubing, which extend beyond the cutting-edges of the shells, but terminate directly upon each side of the break. The shells are slotted to receive the short tubes. These tubes key the shells and form the wireways. Two tubes are preferably used at each breakone for each primary or stem wire; but one tube may be employed, and both the primary or stem wires be carried through the same tube,- or, if but one wire is used and a return is made through the fixture, one tube only will be required. In chandeliers and brackets, where each arm carries both a gasburner and an electric lamp, and the arm is provided with an ornamental covering,within which the wires are run, the shortrseetions of tubing would be used at breaks in such ornamental covering. At the upper oninner end of the fixture the ornamental covering-sleeve is centered and held by a jam-nut turning upon the gaspipe, or by means of a seated joint, and beyond this jam-nut the fixture is supported from the piping of the house,preferably by an insulating-joint, which itself may be seated upon the sleeve to hold the covering parts in place. A canopy or shell is mounted upon the ornamental covering-sleeve by one or more 'setscrews, so as to be adjustable thereon, as described in my patent referred to, and the wires enter the ornamental sleeve within this canopy or shell, and below the insulating-joint. The connections between the fixture and ceiling-wires are made within the canopy or shell, preferably through two safety-catches, one for each side or pole of the circuit. In my patent referred to the ornamental covering-sleeve is shown as provided with holes or slots in the sides of the same at its upper or inner end; but difficulty is experienced in wiring the fixture through such holes or slots. I now provide such sleeve with open-end slots extending through the end of such sleeve. The wires are passed through the sleeve before the jam-nut or joint is turned onto the end of the gas-pipe, and such wires, after being suitably protected to'prevent chafing, are then bent down into the open-end slots, and the j am-nut or j oint turned to place. The ornamental sleeve is usually capable of turning on the gas-pipe, and this axial movement renders the wires which pass through the slots at the upper or inner end of the sleeveliable to have their insulating-covering cut or abraded, or to be cut themselves. To prevent this I key the ornamental sleeve or the upper or inner section of such sleeve,if it is made in more than one section. This,it is evident, may be done in any suitable way. I prefer to notch the lower or outer end of the sleeve (or the upper or inner section thereof) and provide a suitable engaging-stop, which may be a small block or projection formed upon or soldered to the part against which the sleeve abuts at its lower or outer end.

The features of the invention are applicable to gas-fixtures, for remodeling them into combined gas and electric light fixtures, as well as to the original construction of combined fixtures. It is evident, also, that all features of the invention, except, perhaps, the first above described, are applicable to fixtures intended for use for electric lamps only, or to the remodeling of gas-fixtures into electric-light fixtures where it is desired or found advantageous to run the wires through the space between the.

central sustaining-pipe and the ornamental covering, instead ofdirectly through such central sustaining-pipe, and this is likewise true of the invention set forth in my patent referred to.

In the accompanying drawings, forming a part hereof, Figure l is a vertical section of a fixture embodying my invention; Fig. 2, a vertical section, on a larger scale, through the fixture at a break in the ornamental covering; Fig. 3, a horizontal section on line 3 3; Fig. 4, a separate perspective View of the upper or inner end of the covering-sleeve; Fig. 5, a perspective view showing the means for keying the covering-sleeve or the upper or inner section thereof, and Fig. 6 a vertical section of a modified form of fixture.

With reference more particularly to Figs. I to 5, A is the central sustaining-stem or gaspipe, carrying gas-distributing body B, from which project gas-arms O, supporting the ornamental ring D. Below ring D is a shell, a, supported by rod 0, hanging from body B. Above ring D is a shell, 0, which has an inwardly-turned upper edge hugging the pipe A. The electric-lamp arms E project from the ring D, as shown.

F F are sections of an ornamental coveringsleeve, between which there is a break, G, formed, in the instance shown, of three shells, d e f. These shells have inwardly-turned edges 9, Fig. 3, which hug the pipe A. These edges are slotted, as shown, and likewise the hugging-edge of shell 0, and short sections of tubing h are soldered to the pipe A to key the shells and form wireways through the huggingedges of the shells. The pipe Ais secured to the house-pipe H by an insulating-joint, I.

. J is the jam-nut, which turns on the upper end of the pipe A, and centers and holds the section F of the covering-sleeve, while K is the adjustable canopy or shell. The section F of the covering-sleeve has open-end slots 1 cut in its upper end, for the purpose before explained. The lower end of section F has a notch, 75, which engages with a projection, Z, on shell d, thus keying this section of the sleeve. There is no necessity for keying seetion F, although it may be done. If the sleeve were in one section abutting against shell 0, the projection Z would be on that shell.

1 and 2 are primary or stem wires of the fixture, which extend from the canopy through open-end slots-t into section F of the covering-sleeve, through tubes h at break G to section F of covering-sleeve, through tubes h at cutting-edges of shell 0 into the ornamental body, outside of the gasdistributing body. Here the secondary or arm wires 3 4 are secured to the primary wires 1 2, and these secondary wires run in pairs through the electric-lamp arm, or through each of such arms, if more arms than one are used, to the electrio-lamp socket on the end of the arm.

In the canopy the primary fixture-wires are secured to ceiling-wires 5 6, preferably through fusible safety-catches m m.

In Fig. 6 the ornamental body has a top made in one piece with ring D, into which top the pipe A screws, thus supporting the ring D from the pipe A instead of from the gasarms. This body may, however, have a spider-top and be covered by an ornamental shell, in which case tubes h would be required at the cutting or hugging edge of the shell. The electric-lamp arms E iroject from ring D, while an extension, A, of pipe A extends downwardly through the ornamental body and carries the gas-arms O. The shell a, closing the lower side of {the ornamental body, slides upon A, and is held by one or more set-screws, n. The covering-sleeve is shown as made in one section; but it may be made in two or more IIO sections, in which case tubes It would be required at the break or breaks. The coveringsleeve of this fixture has open-end slots at its upper end, and is keyed at its lower end the same as the covering-sleeve of the fixture shown in Figs. 1 to 5.

What I claim is- 1. In a combined gas and electric light fixture made as an integral structure, and having the conducting-wires concealed within its ornamental covering, one or more electriclamp arms extending only to the ornamental body or ring of the fixture, substantially as set forth.

2. In a combined gas and electric light fixture made as an integral structure, the combination, with the main or stem gas-pipe, and one or more gas-arms, of an ornamental body or ring, one or more electric-lamp arms extending only to such ornamental body or ring, primary wires extending through the ornamental covering of the main or stem gaspipe, secondary wires extending through such electric-lamp arms, and connections between the primary and secondary wires within such ornamental body or ring, substantially as set forth.

3. In a fixture having an ornamental covering, and provided with conducting-wires for electric lights running in the space between the pipe and the ornamental covering, and. passing into and out of such space, means for preventing the turning of the ornamental covering at cutting or abrading edges, substantially as set forth.

4. In a fixture wired for electric light, the

combination, with the ornamental covering of such fixture provided with shells having such fixture provided with shells having edges hugging the pipe, of tube-sections at such hugging-edges forming wireways for preventing contact of the wires with such edges, substantially as set forth.

6. In a fixture wired for electric light, the combination, with the ornamental covering of such fixtures provided with shells having edges hugging the pipe, of tube-sections secured to the pipe at such hugging-edges to key the shells and form wireways, substantially as set forth.

7. In a fixture having wires for electric lights passing into the space between the pipe and ornamental covering-sleeve at the upper or inner end of said sleeve, the open-end slot or slots in the end of such sleeve, substantially as set forth.

8. In a fixture having wires for electric lights passing into the space between the pipe and ornamental covering-sleeve through one or moreopenings in such sleeve, means for preventing the turning of such sleeve upon the pipe, substantially as set forth.
